WebAbstract. For many inference problems in statistics and econometrics, the unknown parameter is identified by a set of moment conditions. A generic method of solving moment conditions is the Generalized Method of Moments (GMM). However, classical GMM estimation is potentially very sensitive to outliers. Robustified GMM estimators … WebGeneralized Method of Moments 1.1 Introduction This chapter describes generalized method of moments (GMM) estima-tion for linear and non-linear models with …

For example, linear regression model y i = X iθ+ e i with endogenous regressors X i and instrumental variables Z i: m i (θ) = Z0(y i −X iθ) = Z0e i TheGMM estimatorminimizes a quadratic ... Webweighted Generalized Method of Moments (GMM) [17], a widely popular method in econometrics that uses the moment conditions implied by the IV model to efficiently estimate causal parameters. Leveraging a new variational reformulation of the efficient GMM with optimal weights, we develop a peel shire wa
